Bei known thatl, O'rro ,'CUnLMAn, a

citizen of the United States, and-a resident is a specification. t y I The principal objects of' this 4invention are to obtain a radiator -for automobiles which will use a portion'of the exhaust from the motor for warming purposes, without interfering with the use of the muier or cut-out,

and which maybe substituted for onelo'r more 'of the boards .which formthe floor of the body of the automobile; and further to obtain a device whichl will be simple in construction, and durable and whichwill radiate heat therefrom only onv the upper side Additional objects 'sought by meare to obtain a radiator which is removable, and which provides an adjustment lto control the quantityv of exhaust mixture which is deliveredv thereinto.

A still further object is to obtain a device made .and connected to the exhaust pipeof the motor insuc'h manner as to permlt more than one of said devices to be used in the same car body, and each one of said radiators to be used, independently of the others.

I attain these objects by the mechanism: illustrated in the accompanying drawing, in

Figure 1 is a diagram ofthe chassis of an automobile provided with radiators embodying this invention installed in the iioor.

thereof. Fig. 2 is a vertical section on line l2 2 of Fig. 3, viewed in the direction indicated by the arrows. Fig. 3 is a top planE View of a radiator embodying this invention.

Fig. 41s a'. vertical section on line 4-4 of.i

Fig. 3, viewed in the direction indicated by the arrows. Fig. 5- is a vertical section, on'

section of the exhaust pipe of a motor including the constructions by means of which my device is attached thereto, and of the muiier cut out.

SimilarAv letters refer to .similar parts throu hout the several views.

A, ig. 1, is the'frame of an automobile.;

chassis.;

B 1s l"a `portion of the exhaust pipe of a motor. i

.is a spring onstem C is a .pipe extending' downward from pipe B and in communication therewith at its upper end. l

D is a valve which seats to close th'elower end of pipeC.

d is the valve stem of valve D, d is a button on the upper end of stem d, and d d "yieldingly holding valve 'D seated. j y

E, E', E, are respectively pipes or ccnduits communicating at one en d with pipe C and at vthe other end with the inlet pipes .of the radiators, (said radiators are marked 1, 2, and 3, Iin Fig. 1). F is a frame forming'an element of a.

radiator embodying this invention. I have heretofore made frame F'of wood.

f, f, are broken lines in Fig. 3, indicating the mitered ends of the side and end pieces of the frame F. l

.G is the bottom plate and G plate of the radiator.

H is a sheet of asbestos or other heat insulating material which lis laid or spread over the frame F and bottom plate G. The edges of sheet H are 'interposed between frame F and plate Gr.

I, I, are strips of metal which are laid on the heat insulating material H and exteild from one side of the device to the ot er.

is the top I', I', are strips similar to strips I which the use of the radiator as a bottom board. in

the floor of'an automobile car body, I make the plates G, G', of thin sheet metal secur- 'ingthem to the frame vF by screws L and securmg said plates together by means of the above described construction which includes strips I, I', supports J, bolts K and nuts afto obtain what I term a truss which extends from side to 4side of the radiator. A suitable numberof these trusses are placed :lin therad'i'ator (two are shown in Fig. 3), so

same purposes that the floor of an that the radiator may be walked on or otherwise used in the same manner and for the automobile car body is used. To control the quantity of exhaust mixture delivered to the radiator-embodyin my invention and to permit the removal o the radiator at any time I have devised the construction particularly illustrated in Fig. 2 of the drawing; where the upper end of pipe E terminates' inthe flared mouth M into which the tube m (which tube 'I make of asbestos pipe), is forced when the radiator is in place. The pipe or conduit E and the flared .end M thereof, are secured in the chassis of the automobile andare not readily removed, while the fiexible tubem is removable .from said end M.

Nis a tube or pipe secured in the bottom of the radiator with its lower end inserted in flexible tube m. Tube or pipe N is the inlet to the radiator and O is the outlet.

P is a valve which seats to close the upper end of the pipe N.

p is the stem of valve P. Stem p is provided with screw threads and with the head 70.

Q'is a spring mounted on stem p. By turning the head p in one. direction valve lP is raised or opened from its seat and by turning it in the other direction the valve is seated and the function of the spring Q. is simply to prevent the position of thevalve becoming changed from the jars incidentto the movements of the automobile.

The distance of the valve P from its seat determines the quantity of the heated product-s from the exhaust pipe which enter the radiator, and inl practice a different-quantity of such products is delivered to each one of the radiators in the Hoor.

One 'of the functions of the strips I, I, is to strengthen the plates G, Gr', and where said plates are made sufficiently thick said strips I, I, may be omitted from the construction of the device. In addition to the function above set forth these strips serve as washers at the ends of the supports J.

I claim 1. The combination of a frame, plates attached to the top and bottom of the frame,

4 heat insulating material on the lower plate and on the frame, strips extending from one side of the frame to the other side, beneath the top plate and upon the heat insulating material, supports interposed between the strips and means to hold the plates and strips rigidly to said supports, all arranged moeras tosobta'in a chamber between thevheat insulating material and the upper late, and said chamber provided with an et and an outlet.

2. The combination of a frame, plates at tached to the top and bottom of the frame, heat insulating material on the lower plate and on the frame, stri s extendin from one side of the frame to the other si e, beneath the ltop plate and upon the heat insulating materlal, supports interposed between the strips and means to hold the plates and strips rigidly to said supports, all arranged to obtain a chamber between the heat insulating material and the lupper late, and said chamber provided with an i et and an outlet, a valve arranged to seat to close the inlet, means to move the valve from its seat,

and means to yieldingly hold the valve inan adjusted position.

3. The combination of a frame, plates attached to the top and bottom of the frame, heat insulating material on the lower plate and on the frame, said frame and plates arranged to obtain a chamber between the heat insulating material and the upper plate, strips extending from one side of the frame to the other side, and resting on the sides of the frame and upon the heat insulating material supports 1n said chamber between the upper plate and the strips, and

means to hold said plates and' strips to saidV supports and to force the strips down onto the insulating material to maintain said insulating material in place, said chamber provided with an inlet and with an outlet.

4. The combination of a frame, `plates attached to the top and bottom of the frame, heat insulating material on the lower plate and on the frame` strips extendin from one side of the frame to the other si e beneath the top plate and upon the heat insulating material, supports' interposed between the strips and means to hold the plates and strips rigidly to said supports, all arranged to obtain a chamber between the heat insulating material and the upper late, and said chamber provided with an i et and an outlet, a valve arranged to seat to close the inlet, means to move the valve from its seat, a flexible pipe joined to the bottom plate of the radiator and a stationary flaring pipe arranged to receive said liexible pipe when the radiator is placed thereover.
